Description

Waterproof sweat-proof lasting eyebrow pencil and preparation method thereof
Technical Field
The invention belongs to the technical field of cosmetics. More particularly, it relates to a waterproof sweat-proof durable eyebrow pencil and a preparation method thereof.
Background
The eyebrow pencil lead is made from materials including grease, wax and pigment, wherein the wax is paraffin, Japan wax, beeswax, ozokerite, lanolin, carnauba wax, cocoa butter and the like, the wax mainly has thickening, solidifying and shaping effects in a formula, the melting point of the wax is generally between 45 and 110 ℃, and the wax is required to be melted firstly and then changed into flowing liquid through temperature rise to be mixed with coloring agent, filler and the like when the eyebrow pencil is prepared. But in the subsequent preparation process, the temperature is inevitably reduced for 2 to 3 times, and in the process, the separation of grease and coloring agent is easily caused, and the delamination of the product is caused.
Shellac, also known as shellac, shellac and the like, is a fatty resin, is currently used as a component of legal cosmetics in the countries of the united states, japan and the like, which are leading in cosmetic science and technology, is commonly used in hair-setting products such as hair spray, conditioning hair spray and the like, and is also used in eyeliner cosmetics. But it is not seen to be applied to eyebrow pencils to prevent wax from separating from toner.
In addition, after the eyebrow pencil is made up, the skin of a human body can secrete grease and sweat, and the eyebrow pencil without the waterproof and oil-proof functions can be made up, so that the eyebrow pencil with the waterproof and sweat-proof functions is needed.
Disclosure of Invention
The invention aims to solve the technical problem of overcoming the defects of the existing eyebrow pencil and providing the eyebrow pencil with the waterproof and sweat-proof functions.
The above purpose of the invention is realized by the following technical scheme: a waterproof sweat-proof lasting eyebrow pencil comprises the following components in parts by weight: 10-25 parts of a filler, 20-32 parts of a colorant, 5-15 parts of Japan wax, 3-10 parts of polyethylene glycol wax, 1-5 parts of hydrogenated castor oil and 2-5 parts of glycerol tri (ethyl acetate).
Preferably, the eyebrow pencil comprises the following components in parts by weight: 15-25 parts of a filler, 25-32 parts of a colorant, 10-15 parts of Japan wax, 6-10 parts of polyethylene glycol wax, 2-4 parts of hydrogenated castor oil and 2-4 parts of glycerol tri (ethyl acetate).
Preferably, the eyebrow pencil further comprises shellac.
Preferably, in the eyebrow pencil, the weight ratio of the Japan wax, the polyethylene glycol wax and the shellac is 3: 1-2: 0.1 to 1.5.
Preferably, in the eyebrow pencil, the weight ratio of the Japan wax, the polyethylene glycol wax and the shellac is 3: 1.2: 0.8.
preferably, the colorant is selected from at least one of CI77499, CI77492, CI77491 and CI 77891.
Preferably, the filler is selected from one or both of mica and silica.
Preferably, the filler is silica.
Another object of the present invention is to provide a method for preparing the eyebrow pencil, which comprises the following steps:
s1, mechanically pulverizing Japan wax, polyethylene glycol wax, colorant and filler respectively;
s2, adding the Japan wax and the polyethylene glycol wax into a melting material pot, heating to melt, adding the hydrogenated castor oil and the glycerol tri (ethyl acetate), and stirring and mixing uniformly;
s3, cooling to 60-80 ℃, adding the filler and the colorant, and uniformly stirring; grinding; and (5) molding to obtain the product.
Preferably, the step S1 further includes a step of adding shellac during the mechanical pulverization; the step S2 further includes a step of putting the crushed shellac together with the japan wax and the polyethylene glycol wax into a melting pot.
The invention adopts the Japan wax as the main wax to play the roles of solidification and shaping, but the repeated temperature change in the subsequent process causes the wax to be separated from the colorant, and the product has more heterochromatic spots. It has been unexpectedly found that the addition of shellac can overcome the separation between the wax and the colorant, and the inventors speculate that this may be due to the specific amphiphilic block copolymer nature of shellac. The lac has hydrophilic and hydrophobic parts simultaneously, has a large amount of functional groups such as hydroxyl, carboxyl and the like simultaneously, can serve as a bridging effect between toner and wax, has ionizable carboxyl, has certain polyelectrolyte polymer properties, can provide double-electron-layer stabilization and steric hindrance effects simultaneously, has strong dispersion in a system, and thus plays a role in preventing wax from being separated from a coloring agent.
But the lac is very unstable due to a large number of functional groups, and the product is layered in long-term storage tests. In this regard, the inventors further found through experiments that the addition of the polyethylene glycol wax on the basis of the above results in the improvement of the overall stability of the product, and the effect of the polyethylene glycol wax is considered by the inventors to be mainly due to the stabilizing effect of the polyethylene glycol wax on the shellac.
The invention has the following beneficial effects:
the eyebrow pencil provided by the invention solves the problem of separation of wax and colorant by adjusting the formula composition, and the obtained product has good appearance and stability, has the functions of water resistance and sweat resistance, can effectively keep makeup, is smooth in use, is easy to develop color and has a good use effect.
